Week0 My First Task
Project preferences: 1. Quadcopter 2. Water Ram 3. Knock Knock

Week1 Narrative
My task was to fly the drone and to make Anderson power pole conversions. I was able to connect the drone to my android phone via wifi. The quadcopter does not seem balanced and takes off sideways everytime. I called group members and asked them to bring their quadcopters into class to try to figure this problem out. I started changing the leads on the charger and battery to Anderson power poles. Here is my associated /CDIO/ page

My Second Task
I am going to figure out how to launch the quadcopter straight up. I am going to finish changing the remaining battery leads to Anderson power poles. Some leads will need to be made longer using additional wiring. A tutorial on Anderson power pole conversion (with pictures and videos) will be created.

Week2 Narrative
The quadcopter, on its first flight with the bigger 2200mAh battery, took off vertically upon launch. I could not control the height and the copter continued to fly upwards. I hit emergency and the copter crashed into the grassy yard. After inspection, I found one of the motors was missing a gear. The motor was also positioned in a slant when it is supposed to be upright. A replacement gear was obtained from a broken motor. I had to remove the motor cover and use a hammer's nail remover and a vice-grip wrench to free the gear from the shaft without damaging the teeth. The gear was replaced on the broken copter motor. Upon removing the quadcopter's main structure from the foam surrounding it, I found that the plastic harness in the middle had broken.

My Third task
I am going to test the fixed motor but cannot do that until I reinforce the broken plastic harness or replace it.

Week3 Narrative
My task was to fix the broken central cross. However, while fixing one of the quadcopters with replacement parts, an idea occurred and a new approach was chosen over repairing. Parts could be made using the MakerBot 3-D printer. Gloria, a team member, printed a replacement harness using an existing piece found on /Thingiverse/. We realized a quadcopter could be built from scratch using separate bought materials. To begin the process, I ordered two carbon fiber tubes (40" x 0.22") from /Amazon/. The cost for the two tubes was $11.74 plus shipping and handling. Although one tube length is sufficient for the proposed design for one quadcopter, two were ordered. This may allow the simultaneous development of both the initial proposed design and the alternative design (see CDIO page below). Gloria also printed a leg piece. We will have to wait for the carbon fiber rods to arrive to see if the printed leg will fit. *While waiting for parts to arrive, repair on the existing quadcopters will continue.

My Fourth task
Once the carbon fiber rods arrive, I can begin printing appropriate parts for it or if such parts do not exist, I will have to make the input data myself. Parts that cannot be printed like the arduinos, sensors, wiring and motors will need to be purchased.

Week4 Narrative
No further work with the quadcopters was done since all parts have been given to another group. Each team member's CDIO pages were collected onto one page organized under section "Quad Copter" /Quadcopter/. I made some revisions to my CDIO pages so that the next step will be clear to the next group working on the project.
